06 Cummins Ram 5.9L 6,791 miles 2yrs Rotella 5w-40

Truck was used very few miles over the last 25 months, but has a BullyDog tuner, S&B air intake (oiled type reusable filter) and intake manifold. 414RWHP 800ft/lbs RWTQ .

I was happy to see below average silicon indicating the S&B air filter is a good one. I used Rotella T6 5W-40 synthetic with a Donaldson Endurance oil filter.

That report looks pretty good. That oil looks to hve a real good additive package. Not to get too off topic, but since you have an 06 you should really look into efi live you would think it's a whole new truck and they tend to get better mpg with a custom tune instead of a canned tune. Check out anarchy or silverbullet tuning.

A decent UOA. But T6 should be able to go 12K to 18K. Not sure your TBN would support that. I looked back at my UOA for my 1999 Cummins and the TBN was higher at 11.7K miles.

But your lab was Blackstone and I used Polaris.

Well, this oil was in for slightly over 2 years, I'm sure that effected the TBN and pH a bit.
